焊接專機在經過一段時間的使用后，總會因為種種原因出現故障。當確定故障部位后再進行檢修和更換，解決產生的故障，使焊接設備盡快投入使用，減少因設備故障而造成的經濟損失。下面來講講山東焊接專機的直觀檢查方法吧。

After a period of use, welding machines will always malfunction due to various reasons. After determining the fault location, maintenance and replacement should be carried out to solve the resulting faults, so that the welding equipment can be put into use as soon as possible and reduce the economic losses caused by equipment failures. Next, let's talk about the visual inspection method of Shandong welding machine.

直觀法是根據電器元件故障的外部表現，通過看、聞、聽等手段檢查判斷故障的方法。維修檢查步驟：

The intuitive method is a method of checking and judging faults based on the external manifestations of electrical component faults through means such as seeing, smelling, and listening. Maintenance and inspection steps:

①調查情況：向操作者和故障發生時的在場人員詢問情況，包括故障外部表現、大致部位以及發生故障時的環境情況。如有無異常操作、明火、熱源等是否靠近電器元器件、有無腐蝕性氣體侵入、有無漏水、是否有人修理過以及修理的內容等。

① Investigation situation: Ask the operator and the personnel present at the time of the fault, including the external manifestations of the fault, the approximate location, and the environmental conditions at the time of the fault. If there are any abnormal operations, whether open flames, heat sources, etc. are close to electrical components, whether there is corrosive gas invasion, whether there is water leakage, whether someone has repaired, and the repair content.

②初步檢查：根據調查的情況，查看有關電器元器件外部有無損壞、連線有無斷路、松動，絕緣有無燒焦，螺旋熔斷器的熔斷指示器是束跳出，電器元器件有無進水和油垢，開關位置是否正確等。

② Preliminary inspection: Based on the investigation, check whether there is external damage to the electrical components, whether the wiring is open or loose, whether the insulation is burnt, whether the fuse indicator of the spiral fuse is bundle jumping out, whether the electrical components have water and oil stains, and whether the switch position is correct.

③試焊：通過初步檢查，確認沒有可能使故障進一步擴大和造成人身、設備事故后，可以通電。穩定無異常情況后，可進一步做焊接試驗檢查，

③ Trial welding: After confirming through preliminary inspection that there is no possibility of further expansion of the fault or causing personal or equipment accidents, power can be applied. After stable and without any abnormal conditions, further welding test inspections can be conducted,

焊機在正常工作中要注意有無嚴重跳水、異常氣味和異常聲音等現象，一經發現應立即停止，切斷電源。注意檢查電器元器件的溫升及電器元器件的動作程序是否符合焊接設備原理圖的要求，從而發現故障部位。更多相關事項就來我們網站http://www.fangzh.cn咨詢吧！

During normal operation of the welding machine, attention should be paid to whether there are serious diving, abnormal odors, and abnormal sounds. Once found, it should be immediately stopped and the power should be cut off. Pay attention to checking the temperature rise of electrical components and whether the action program of electrical components meets the requirements of the welding equipment schematic diagram, in order to identify the faulty part.
